Your real email is like your home address—once it's out there, you can't take it back.
In an era when every online transaction quietly trades personal identity for access, Proton Mail has introduced email aliases — a quiet but meaningful tool that lets users offer the internet a proxy self rather than their true one. The feature, available in early 2024 to Proton Mail's growing base of privacy-conscious users, reflects a broader cultural reckoning with how freely we surrender our digital identities to services that may not deserve them. Ten aliases for free accounts, unlimited for paid subscribers — a small architecture of protection built against the slow erosion of inbox sovereignty.
- Every online signup is a quiet surrender — your real email address handed to retailers, platforms, and newsletters that may sell or abuse it without consequence.
- Proton Mail's new alias feature disrupts this dynamic by letting users generate disposable addresses that forward to their real inbox, keeping their primary identity hidden.
- The tension is practical: spam accumulates, data breaches expose contact lists, and companies treat inboxes like advertising real estate — aliases offer a delete button for all of it.
- Free users get ten aliases to work with; paid subscribers get unlimited, and each alias can be labeled, filtered, and killed independently when a service oversteps.
- The feature lands in a crowded but growing space — Apple's Hide My Email and Firefox Relay do similar work — signaling that disposable email addresses are becoming a mainstream privacy expectation.
Every time you sign up for something online, you hand over your email address — to retailers, social networks, newsletters — and with it, a small piece of your digital identity. Proton Mail, the encrypted email service built as a privacy-first alternative to Gmail and Outlook, has now added a feature designed to interrupt that habit.
The tool is called email aliases. You generate a fake address inside Proton Mail, use it wherever a signup form demands an email, and messages sent to it arrive in your regular inbox anyway. When a service starts flooding you with spam, or when you simply want to cut ties, you delete the alias. Your real address never surfaces.
The technology itself isn't new — Apple's Hide My Email, Gmail's plus-sign workaround, and Firefox Relay all occupy similar ground. But Proton Mail's implementation is clean and accessible, particularly for users already inside their ecosystem. Paid accounts get unlimited aliases; free accounts get ten.
The practical value compounds over time. Assign a unique alias to every service you join, and you'll quickly learn which companies respect your inbox and which treat it as a billboard. Delete an alias and you've severed that company's access entirely. You can organize aliases by category — shopping, newsletters, social media — and filter accordingly.
Setting one up takes minutes: log into the web version, find the Security Center in the sidebar, and select "Create an alias." Name it, add a note, and Proton Mail generates a randomized disposable address ready to paste into any form.
The shift is subtle but real. Rather than handing your identity to every website that asks for it, you're offering a temporary proxy — one you can revoke without consequence. It's a small rebalancing of a power dynamic that has long tilted away from the user.
Every time you sign up for something online, you hand over your email address. A retailer asks for it at checkout. A social network wants it to create your account. A newsletter promises exclusive deals if you subscribe. Each time, you're making a choice: give them your real address, or give them something else.
Proton Mail, the encrypted email service that positions itself as a privacy-focused alternative to Gmail and Outlook, has now added a tool to help you choose the "something else" option. The feature is called email aliases, and it works like this: you generate a fake email address inside Proton Mail, use that fake address whenever you sign up for something, and all the messages sent to it land in your regular inbox anyway. When you're done with a service, or when the spam gets too thick, you delete the alias and move on. Your real email address stays hidden.
This isn't new technology. Apple offers something similar through its Hide My Email service. Gmail has a workaround using plus signs and dots. Firefox Relay does much the same thing. But Proton Mail's implementation is straightforward enough that it's worth understanding, especially if you're already using their service. A paid Proton Mail account lets you create as many aliases as you want. Free accounts get ten.
The appeal is practical and psychological both. On the practical side: if you create a separate alias for every service you sign up to, you can immediately tell which companies are respecting your inbox and which ones are drowning it in marketing emails. Delete the alias, and you've cut off that company's ability to reach you. You can also organize aliases by purpose—one for shopping, one for social media, one for newsletters—and filter your inbox accordingly. On the psychological side, there's something satisfying about maintaining a boundary between your real identity and the dozens of digital services that want a piece of your attention.
Setting up an alias in Proton Mail takes a few minutes. Log into the web version, click the shield icon labeled "Security center" in the right sidebar, and select "Create an alias." A dialog box appears where you name the alias—something descriptive, like "Amazon" or "Newsletter signup"—and add a note to yourself about why you created it. Proton Mail then generates a random string of characters attached to your alias name, and that's your disposable address. Copy it, paste it into whatever form you're filling out, and you're done.
The real value emerges over time. After a few months of using aliases, you'll have a clear picture of which services respect your attention and which ones treat your inbox like a billboard. You can retire aliases without guilt. You can experiment with new services without exposing your primary email address to the risk of a data breach or a company selling your contact information to third parties. It's a small tool, but it shifts the power dynamic slightly in your favor. Instead of handing over your identity to every website that asks for it, you're handing over a temporary proxy. The difference is small in theory but meaningful in practice.

Why would someone actually use this instead of just giving out their real email?
Because your real email is like your home address. Once it's out there, you can't take it back. An alias is like a temporary mailbox you can throw away.
But doesn't that seem like a lot of work—creating and managing all these fake addresses?
At first, maybe. But after a month, you realize you've got a clear map of who's actually respecting your inbox and who's just harvesting your attention.
What happens if a company you gave an alias to gets hacked?
That alias is compromised, not your real email. You delete it and move on. The hackers have a dead address.
So it's really about control?
Exactly. You're not hiding from legitimate companies. You're controlling what information they get and how long they can use it.
Is Proton Mail the only option?
No. Apple, Firefox, Gmail all have versions of this. But Proton's is clean and unlimited on paid plans, which matters if you're serious about it.
